Description

Potassium 5-Formyl-2-Thiophenetrifluoroborate is a high-purity organotrifluoroborate salt, a versatile and stable building block in modern synthetic chemistry. Its value lies in its role as a key intermediate for Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex thiophene-containing molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries developing novel active ingredients and advanced organic electronic materials.

Application

• Pharmaceutical Intermediate: A crucial building block for synthesizing novel drug candidates, particularly those containing functionalized thiophene cores for therapeutic applications.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the thiophene moiety can impart specific biological activity.
• Materials Science Research: Serves as a precursor for creating conjugated polymers and small molecules for organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and semiconductors.
• Suzuki-Miyaura Cross-Coupling: Acts as a stable, air- and moisture-tolerant organoboron reagent for palladium-catalyzed carbon-carbon bond formation with various aryl/heteroaryl halides.
• Chemical Synthesis: Employed in academic and industrial R&D for the modular construction of complex, multi-substituted thiophene derivatives and heterocyclic compounds.
• Ligand and Catalyst Development: Useful for preparing functionalized ligands or metal-organic frameworks (MOFs) with tailored properties.

Quality Control

Our Potassium 5-Formyl-2-Thiophenetrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹³C, ¹⁹F), HPLC, and KF titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with full specification data are provided to guarantee compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to handle the material under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to ambient moisture. Recommended storage temperature: 2-8°C.
